Reporter: abevan | Owner: grass-...@…
Type: defect | Status: new
Priority: normal | Milestone: 7.0.0
Component: Raster | Version: svn-trunk
Keywords: r.drain | Platform: MacOSX
Cpu: OSX/Intel |
-----------------------+----------------------------------------------------
GRASS 7.0.svn (spearfish):~ > r.walk -k -n elevation=elevation.10m
friction=elevation.10m coordinate=603289,4925264 output=anisoA
outdir=anisoAdir lambda=0

Walking costs are a=0.720000 b=6.000000 c=1.999800 d=-1.999800
Lambda is 0.000000
Slope_factor is -0.212500
--------------------------------------------
Will need at least 9.23 MB of disk space
Will need at least 12.29 MB of memory
